Blizzard Entertainment returned to Diablo III at the end of June. The developers recently announced the launch of Season 39, "Shadows of the Nephalem." According to the lore, the Nephalem will once again wield the powers of shadows, which players first encountered in Season 22.
Season 39 will feature rewards previously introduced in Diablo III Season 15. In addition to the chest piece and gloves from the exclusive Conqueror set, players will be able to acquire portrait frames inspired by the "relentless Eternal Conflict" for their collection. The Belphegor pet will also be available, which "will gladly help you acquire gold during your travels through Sanctuary."
Upon completing the entire Season Journey, players will receive two new cosmetic items: the "Corpse Dog" and the "Crown of Knowledge" portrait frame.
Blizzard Entertainment also showcased the class item sets from Haedrig's Gifts (which can be obtained by completing certain chapters of the Season Journey):
